      Perfect!!

      Love how simple and streamlined these look! I have older Capris in triple white and Poudre that I love, but wanted something even more streamlined. These fit the bill perfectly!

      I’ve tried everything worth trying and Koios Portofino are perfect in every way!

      I tried Common Projects and returned them, I tried Oliver Cabell twice and returned them, got my first pair of Koios and this fit and look perfect! Well done! For the perfect fit size a full size down. I wear and 13 and 12 fots like a glove.

      Too narrow

      Material was good, a little thin and though compared to vans. I really wanted to like these shoes as they are beautiful however they were too narrow. I have somewhat wide feet. I made a return from a 9 to a 10 and they were still too narrow. Hopefully they will have a wide version in the future.

      Good buy

      The portofinos are very high quality shoes. On the good advice of KOIO's consultant, I ordered a half size down, 11, from my normal size.
